Original problem:
To create an HTML version of a mail message I do:

StreamReader htmlStream = new StreamReader(html.GetReport(),
Encoding.UTF8);

MailMessage mail = new MailMessage();

mail.AlternateViews.Add(new AlternateView(htmlStream.BaseStream,
MediaTypeNames.Text.Html));

The mail when it arrives has the characters 0xEF, 0xBB, 0xBF (which
are the preamble chars). And the StreamReader has them as it's
preamble.

The problem is, they show up on the page of the email. So MailMessage
does not know to not display them.

So I tried getting rid of the StreamReader and did:

string htmlMailMsg =
Encoding.UTF8.GetString(((MemoryStream)html.GetRep ort()).GetBuffer());
MemoryStream ms = new
MemoryStream(Encoding.ASCII.GetBytes(htmlMailMsg)) ;
mail.AlternateViews.Add(new AlternateView(ms,
MediaTypeNames.Text.Html));

Now I get a ? at the top of the message. The memory stream has no
preamble as best as I can tell.

Any idea how to avoid this?

thanks - dave

Hello Dave

(MemoryStream)html.GetReport()).GetBuffer() returns a byte array of the
message. If you do not intend to display the preamble bytes (0xEF, 0xBB,
0xBF), could you remove those bytes from this byte array? For example:

byte[] data = new byte[] { 0xa, 0xb, 0xc, 0xEF, 0xBB, 0xBF,
0x1, 0x2, 0x3 };
List<byte> list = new List<byte>(data.Length);
foreach (byte b in data)
{
if (b != 0xEF && b!= 0xBB && b!= 0xBF)
list.Add(b);
}
byte[] result = list.ToArray();

Hello Dave

What was html.GetReport()).GetBuffer() encoded? Unicode or ASCII? Could it
be that it was encoded in Unicode and removing each character requires
deleting two or three bytes instead of one? For example,

byte[] barr = new byte[] { 0x22, 0x8c, 0x22, 0x8c };
string result = Encoding.Unicode.GetString(barr);

This outputs the chinese characters for "xie xie" (thanks). If we just
remove 0x8c from the byte array, the rest two 0x22 constitute a new unicode
word that does not make sense.
